RESUMO

OBJECTIVE: To analyse the effect of community-based counselling on feeding patterns during the first 12 weeks after birth, and to study whether the effect differs by maternal HIV status, educational level or household wealth. DESIGN: Cluster-randomized trial with fifteen clusters in each arm to evaluate an integrated package providing two pregnancy and five postnatal home visits delivered by community health workers. Infant feeding data were collected using 24 h recall of nineteen food and fluid items. SETTING: A township near Durban, South Africa. SUBJECTS: Pregnant women (1894 intervention and 2243 control) aged 17 years or more. RESULTS: Twelve weeks after birth, 1629 (intervention) and 1865 (control) mother-infant pairs were available for analysis. Socio-economic conditions differed slightly across intervention groups, which were considered in the analyses. There was no effect on early initiation of breast-feeding. At 12 weeks of age the intervention doubled exclusive breast-feeding (OR=2·29; 95 % CI 1·80, 2·92), increased exclusive formula-feeding (OR=1·70; 95 % CI 1·28, 2·27), increased predominant breast-feeding (OR=1·71; 95 % CI 1·34, 2·19), decreased mixed formula-feeding (OR=0·68; 95 % CI 0·55, 0·83) and decreased mixed breast-feeding (OR=0·54; 95 % CI 0·44, 0·67). The effect on exclusive breast-feeding at 12 weeks was stronger among HIV-negative mothers than HIV-positive mothers (P=0·01), while the effect on mixed formula-feeding was significant only among HIV-positive mothers (P=0·03). The effect on exclusive feeding was not different by household wealth or maternal education levels. CONCLUSIONS: A perinatal intervention package delivered by community health workers was effective in increasing exclusive breast-feeding, exclusive formula-feeding and decreasing mixed feeding.

RESUMO

BACKGROUND: Progress towards MDG4 for child survival in South Africa requires effective prevention of mother-to-child transmission (PMTCT) of HIV including increasing exclusive breastfeeding, as well as a new focus on reducing neonatal deaths. This necessitates increased focus on the pregnancy and early post-natal periods, developing and scaling up appropriate models of community-based care, especially to reach the peri-urban poor. METHODS: We used a randomised controlled trial with 30 clusters (15 in each arm) to evaluate an integrated, scalable package providing two pregnancy visits and five post-natal home visits delivered by community health workers in Umlazi, Durban, South Africa. Primary outcomes were exclusive and appropriate infant feeding at 12 weeks post-natally and HIV-free infant survival. RESULTS: At 12 weeks of infant age, the intervention was effective in almost doubling the rate of exclusive breastfeeding (risk ratio 1.92; 95% CI: 1.59-2.33) and increasing infant weight and length-for-age z-scores (weight difference 0.09; 95% CI: 0.00-0.18, length difference 0.11; 95% CI: 0.03-0.19). No difference was seen between study arms in HIV-free survival. Women in the intervention arm were also more likely to take their infant to the clinic within the first week of life (risk ratio 1.10; 95% CI: 1.04-1.18). CONCLUSIONS: The trial coincided with national scale up of ARVs for PMTCT, and this could have diluted the effect of the intervention on HIV-free survival. We have demonstrated that implementation of a pro-poor integrated PMTCT and maternal, neonatal and child health home visiting model is feasible and effective. This trial could inform national primary healthcare reengineering strategies in favour of home visits. The dose effect on exclusive breastfeeding is notable as improving exclusive breastfeeding has been resistant to change in other studies targeting urban poor families.

RESUMO

Breastfeeding is widely endorsed as the optimal strategy for feeding newborns and young infants, as well as improving child survival and achieving Millennium Development Goal 4. Exclusive breastfeeding (EBF) for the first 6 months of life is rarely practised in South Africa. Following the 2010 World Health Organization (WHO) infant feeding recommendations (EBF for HIV-positive mothers with maternal or infant antiretroviral treatment), South Africa adopted breastfeeding promotion as a National Infant Feeding Strategy and removed free formula milk from the Prevention of Mother-to-Child Transmission of HIV programme. This study aimed to explore the perceptions of mothers and household members at community level regarding the value they placed on formula feeding and circumstances that drive the practice in a peri-urban community. We conducted in-depth interviews with HIV-positive and HIV-negative mothers in a community-randomised trial (Good Start III). Focus group discussions were held with grandmothers, fathers and teenage mothers. Data were analysed using thematic analysis. The following themes were identified; inadequate involvement of teenage mothers; grandmothers who become replacement mothers; fear of failing to practise EBF for 6 months; partners as formula providers and costly formula milk leading to risky feeding practices. The new South African Infant Feeding Strategy needs to address the gaps in key health messages and develop community-orientated programmes with a focus on teenage mothers. These should encourage the involvement of grandmothers and fathers in decision-making about infant feeding so that they can support EBF for optimal child survival.

RESUMO

BACKGROUND: Globally, 40% of the 7.6 million deaths of children under five every year occur in the neonatal period (first 28 days after birth). Increased and earlier recognition of illness facilitated by community health workers (CHWs), coupled with effective referral systems can result in better child health outcomes. This model has not been tested in a peri-urban poor setting in Africa, or in a high HIV context. METHODS: The Good Start Saving Newborn Lives (SNL) study (ISRCTN41046462) conducted in Umlazi, KwaZulu-Natal, was a community randomized trial to assess the effect of an integrated home visit package delivered to mothers by CHWs during pregnancy and post-delivery on uptake of PMTCT interventions and appropriate newborn care practices. CHWs were trained to refer babies with illnesses or identified danger signs. The aim of this sub-study was to assess the effectiveness of this referral system by describing CHW referral completion rates as well as mothers' health-care seeking practices. Interviews were conducted using a structured questionnaire with all mothers whose babies had been referred by a CHW since the start of the SNL trial. Descriptive analysis was conducted to describe referral completion and health seeking behaviour of mothers. RESULTS: Of the 2423 women enrolled in the SNL study, 148 sick infants were referred between June 2008 and June 2010. 62% of referrals occurred during the first 4 weeks of life and 22% between birth and 2 weeks of age. Almost all mothers (95%) completed the referral as advised by CHWs. Difficulty breathing, rash and redness/discharge around the cord accounted for the highest number of referrals (26%, 19% and 17% respectively). Only16% of health workers gave written feedback on the outcome of the referral to the referring CHW. CONCLUSIONS: We found high compliance with CHW referral of sick babies in an urban South African township. This suggests that CHWs can play a significant role, within community outreach teams, to improve newborn health and reduce child mortality. This supports the current primary health care re-engineering process being undertaken by the South African National Department of Health which involves the establishment of family health worker teams including CHWs. TRIAL REGISTRATION NUMBER: ISRCTN41046462.

RESUMO

BACKGROUND: To investigate the feasibility, the ease of implementation, and the extent to which community health workers with little experience of data collection could be trained and successfully supervised to collect data using mobile phones in a large baseline survey METHODS: A web-based system was developed to allow electronic surveys or questionnaires to be designed on a word processor, sent to, and conducted on standard entry level mobile phones. RESULTS: The web-based interface permitted comprehensive daily real-time supervision of CHW performance, with no data loss. The system permitted the early detection of data fabrication in combination with real-time quality control and data collector supervision. CONCLUSIONS: The benefits of mobile technology, combined with the improvement that mobile phones offer over PDA's in terms of data loss and uploading difficulties, make mobile phones a feasible method of data collection that needs to be further explored.

RESUMO

In light of South Africa's generalized HIV/AIDS epidemic coupled with high infant mortality, we undertook a cluster Randomized Control Trial (2008-10) assessing the effect of Community Health Worker (CHW) antenatal and postnatal home visits on, amongst other indicators, levels of HIV-free survival, and exclusive and appropriate infant feeding at 12 weeks. Cost and time implications were calculated, by assessing the 15 participating CHWs, using financial records, mHealth and interviews. Sustainability and scalability were assessed, enabling identification of health system issues. The majority (96%) of women in the community received an average of 4.1 visits (target seven). The paid, single purpose CHWs spent 13 h/week on the programme. The financial cost per mother amounted to $94 ($23 per home visit). Modelling target coverage (95% mothers, seven visits) and increased efficiency showed that if CHWs spent 25 h/week on the programme, the number of CHWs required would decrease from 15 to 12. The intervention almost doubled exclusive breastfeeding (EBF) at 12 weeks and showed a 6% relative increase in EBF with each additional CHW visit. Home visit programmes improve access and prevention but are not an inexpensive alternative: the observed cost per home visit is twice that of a clinic visit and in target/efficiency scenario decreases to 70% of the cost of a clinic visit. Ensuring sustainability requires optimizing the design of programmes and deployment of human resources, whilst maintaining impact. However, low remuneration of CHWs leads to shorter working hours, low motivation and sub-optimal coverage even in a situation with well-resourced supervision. The community-based care programme in South-Africa is based on multi-purpose CHWs, its cost and impact should be compared with results from this study. Quality of support for multi-purpose CHWs may be the biggest challenge to address to achieving higher efficiency of community-based services. TRIAL REGISTRATION NUMBER: ISRCTN41046462.

RESUMO

BACKGROUND: In 2001, South Africa began implementing the Prevention of Mother-to-Child Transmission of HIV (PMTCT) programme. This programme included distribution of free formula milk for infants up to 6 months of age at all public health facilities. Effective from 1 January 2011, KwaZulu-Natal became the first province to phase out free formula milk from its PMTCT programme. On 23 August 2011, the South African National Department of Health adopted promotion of exclusive breastfeeding as the national infant feeding strategy and made a decision to withdraw free formula milk from the PMTCT programme. OBJECTIVE: To explore the perceptions and understanding of households at community level on the policy decision to phase out free formula milk from the PMTCT programme in South Africa. METHODS: An exploratory qualitative study was conducted amongst women enrolled in a community randomized trial known as Good Start III. Focus group discussions were held with grandmothers, fathers and teenage mothers; and in-depth interviews were performed with HIV-positive and HIV-negative mothers. Data were analysed using thematic analysis. RESULTS: Identified themes included: (1) variations in awareness and lack of understanding of the basis for the policy change, (2) abuse of and dysfunctional policy as perceived reasons for policy change and (3) proposed strategies for communicating the policy change. CONCLUSION: There is an urgent need to develop a multifaceted communication strategy clearly articulating the reasons for the infant feeding policy change and promoting the new breastfeeding strategy. The communication strategy should take into account inputs from the community. With a supportive environment and one national infant feeding strategy, South Africa has an opportunity to reverse years of poor infant feeding practices and to improve the health of all children in the country.

RESUMO

INTRODUCTION: We will be unable to achieve sustained impact on health outcomes with community health worker (CHW)-based interventions unless we bridge the gap between small scale efficacy studies and large scale interventions. Effective strategies to support the management of CHWs are central to bridging the gap. Mobile phones are broadly available, particularly in low and middle income countries (LAMIC's), where the penetration rate approaches 100%. In this article we describe how mobile phones may be combined with mobile web-based technology to assist in the management of CHWs in two projects in South Africa. METHODS: This paper is a descriptive one, drawing lessons from two Randomised Controlled Trials (RCT's), outlining how a mobile phone information system can be utilized to enhance the quality of health interventions. We organized our comprehensive management and supervision system around a previously published management framework. The system is composed of mobile phones utilized by CHWs and a web-based interface utilized by CHW supervisors. Computerized algorithms were designed with intervention and assessment protocols to aid in the real-time supervision and management of CHWs. RESULTS: CHWs used mobile phones to initiate intervention visits and trigger content to be delivered during the course of intervention visits. Supervisors used the web-based interface for real-time monitoring of the location, timing, and content of intervention visits. Additional real-time support was provided through direct support calls in the event of crises in the field. CONCLUSION: Mobile phone-based information system platforms offer significant opportunities to improve CHW-delivered interventions. The extent to which these efficiency gains can be translated into realized health gains for communities is yet to be tested.

RESUMO

BACKGROUND: Progress towards MDG4 in South Africa will depend largely on scaling up effective prevention against mother to child transmission (PMTCT) of HIV and also addressing neonatal mortality. This imperative drives increasing focus on the neonatal period and particularly on the development and testing of appropriate models of sustainable, community-based care in South Africa in order to reach the poor. A number of key implementation gaps affecting progress have been identified. Implementation gaps for HIV prevention in neonates; implementation gaps for neonatal care especially home postnatal care; and implementation gaps for maternal mental health support. We have developed and are evaluating and costing an integrated and scaleable home visit package delivered by community health workers targeting pregnant and postnatal women and their newborns to provide essential maternal/newborn care as well as interventions for Prevention of Mother to Child Transmission (PMTCT) of HIV. METHODS: The trial is a cluster randomized controlled trial that is being implemented in Umlazi which is a peri-urban settlement with a total population of 1 million close to Durban in KwaZulu Natal, South Africa. The trial consists of 30 randomized clusters (15 in each arm). A baseline survey established the homogeneity of clusters and neither stratification nor matching was performed. Sample size was based on increasing HIV-free survival from 74% to 84%, and calculated to be 120 pregnant women per cluster. Primary outcomes are higher levels of HIV free survival and levels of exclusive and appropriate infant feeding at 12 weeks postnatally. The intervention is home based with community health workers delivering two antenatal visits, a postnatal visit within 48 hours of birth, and a further four visits during the first two months of the infants life. We are undertaking programmatic and cost effectiveness analysis to cost the intervention. DISCUSSION: The question is not merely to develop an efficacious package but also to identify and test delivery strategies that enable scaling up, which requires effectiveness studies in a health systems context, adapting and testing Asian community-based studies in various African contexts.

RESUMO

We describe a number of pitfalls that may occur with the push to rapidly expand access to antiretroviral therapy in sub-Saharan Africa. These include undesirable opportunity costs, the fragmentation of health systems, worsening health care inequities, and poor and unsustained treatment outcomes. On the other hand, AIDS "treatment activism" provides an opportunity to catalyze comprehensive health systems development and reduce health care inequities.However, these positive benefits will only happen if we explicitly set out to achieve them. We call for a greater commitment toward health activism that tackles the broader political and economic constraints to human and health systems development in Africa, as well as toward the resuscitation of inclusive and equitable public health systems.
